after the latest patches on msvfw32, I made some further testings. Those
show that, in particular, that ICInfo shouldn't actually open the driver
to this patch:
- makes ICInfo implementation closer to Windows behavior (i.e. no longer
opens the driver)
- fixes most endianess related bugs in fourCC handling (do not rely on
FOURCC <=> char position)
- adds debug function for printing fourCC:s
- makes a few internal function fixes and speed-ups
